My sisters now-ex boyfriend decided to pack up and leave, which is awesome.

Long story, he is a massive pain in the a** and decided to take my sisters car keys... The keys to my BA. (I own it, she drives it)

So I get a long winded crying phone call from the girl going on about how she can't drive to work and all that kind of stuff, sigh.

Anyway, turns out the guys an idiot, he stole the remotes for the car, not the keys themselves... So she's still driving around and everything OK. I'd like a new remote though, as the key doesn't unlock all of the doors at once, which is a bit of a pain in the a**, she needs to shuffle her baby in and out of the rear seat

How hard/expensive is it to get a new remote?

Cheers

The remote you can buy from your Ford Dealer and the programming is straight forward. The instructions are in the owners handbook.
